Abstract
The invention discloses a protector for a stamping tool. The protector comprises an upper die base and a lower die base facing each other. The edge of the upper die base and the edge of the lower die base are provided with guide holes facing one another. At least two lifting devices are arranged between the guide holes. Each lifting device comprises a fixing sleeve, a fixing pin and a hydraulic link. One end of each hydraulic link is disposed inside the corresponding fixing sleeve and is fixed on the lower die base through the corresponding fixing pin. Therefore, the protector has the advantages that the tool can be protected to reduce wear through the buffering action of the hydraulic links during the stamping process.
Description
Technical field
The present invention relates to the diel field, particularly relate to a kind of protective device of diel.
Background technology
Through long stamping procedure, diel all can have wearing and tearing to a certain degree, traditional mould, have with alignment pin or be threaded, usually after long-time punching press, can cause loosening and wearing and tearing, thereby affect machining accuracy.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of protective device of diel, can to diel, be protected for a long time, reduces the wearing and tearing of mould.
For solving the problems of the technologies described above; the technical scheme that the present invention adopts is: the protective device that a kind of diel is provided; comprise: the upper bolster be oppositely arranged and die shoe; described upper bolster offers relative pilot hole with the die shoe marginal position; place at least two lowering or hoisting gears between described pilot hole; described lowering or hoisting gear comprises fixed cover, steady pin and hydraulic connecting rod; described hydraulic connecting rod one end is built in fixed cover; by described steady pin, be fixed on die shoe, described hydraulic connecting rod is connected with a sensor.
In a preferred embodiment of the present invention, described hydraulic connecting rod lower end connecting fluid cylinder pressure, described hydraulic cylinder is arranged on die shoe inside.
In a preferred embodiment of the present invention, described pilot hole is divided into two kinds, i.e. the first pilot hole and the second pilot hole, and described the first pilot hole and the second pilot hole are mutually corresponding, described the first pilot hole is opened on upper bolster, and described the second pilot hole is opened on die shoe.
In a preferred embodiment of the present invention, described hydraulic connecting rod upper end is fixed by a pin in described the first pilot hole, and the lower end interference of described hydraulic connecting rod is connected in fixed cover, then with steady pin, fixed cover is fixed on die shoe.
The invention has the beneficial effects as follows: energy punch press of the present invention, in the mould punching process, is protected mould in time, reduces the wearing and tearing of mould, extends the life-span of mould.
The accompanying drawing explanation
Fig. 1 is the perspective view of protective device one preferred embodiment of diel of the present invention;
In accompanying drawing, the mark of each parts is as follows: 1, upper bolster, 2, die shoe, 3, pilot hole, the 301, first pilot hole, the 302, second pilot hole, 4, lowering or hoisting gear, 5, fixed cover, 6, steady pin, 7, hydraulic connecting rod, 8, hydraulic cylinder, 9, pin.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1, the embodiment of the present invention comprises:
A kind of protective device of diel; comprise: the upper bolster 1 be oppositely arranged and die shoe 2; described upper bolster 1 offers relative pilot hole 3 with die shoe 2 marginal positions; place at least two lowering or hoisting gears 4 between described pilot hole 3; described lowering or hoisting gear 4 comprises fixed cover 5, steady pin 6 and hydraulic connecting rod 7; described hydraulic connecting rod 7 one ends are built in fixed cover 5, by described steady pin 6, are fixed on die shoe 2, and described hydraulic connecting rod 7 is connected with a sensor.
In addition, described hydraulic connecting rod 7 lower end connecting fluid cylinder pressures 8, described hydraulic cylinder 8 is arranged on die shoe 2 inside.
In addition, described pilot hole 3 is divided into two kinds, i.e. the first pilot hole 301 and the second pilot hole 302, and described the first pilot hole 301 and the second pilot hole 302 are mutually corresponding, described the first pilot hole 301 is opened on upper bolster 1, and described the second pilot hole 302 is opened on die shoe 2.
In addition, described hydraulic connecting rod 7 upper ends are fixed in described the first pilot hole 301, and fixing with pin 9, described hydraulic connecting rod 7 lower end interference are connected in fixed cover 5, then with steady pin 6, fixed cover are fixed on die shoe 2.
When stamping procedure, upper bolster 1 and die shoe 2 drive hydraulic connecting rod 7 runnings, and hydraulic connecting rod 7 plays a buffer protection function, reduces the wearing and tearing to mould.
The foregoing is only embodiments of the invention; not thereby limit the scope of the claims of the present invention; every equivalent structure or conversion of equivalent flow process that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in scope of patent protection of the present invention.
